Description

Frequency counter based on the microphone input. Counts when theinput rises or falls past a set level and converts into intofrequency or a time period. FOR INDICATION ONLY. Results depend onyour device and its hardware. If you just want to know thefrequency of a sound with harmonics (e.g. mucial instrument), a FFTbased app such as keuwlsofts spectrum analyser or guitar tuner(both free) will be better. This app can provide more accuratefrequency measurement for single frequency input signals. Featuresinclude:Display of triggered event count and frequency or timeperiod.Graph of input signal, 2.5 ms/div up to 640 ms/div.Gate timeof 0.1s, 1s, 10s or 100s.Gain from x1 to x1000.Trigger on rise orfall.AC or DC coupling.Set a noise level so new event is nottriggered until the signal has first passed this level.More detailscan be found on the website.

Dual channel function / waveform / signal generator for the speaker/ headphone audio output.No Ads, No Permissions, No In AppPurchasing, No Limited Features. Full Version.Output is 16 bit foreach left and right channels and at 44.1kHz. Output will depend onyour device hardware. Some device hardware may may filter out theDC bias and low frequency signals. At high frequencies, thewaveforms will be distorted due to limited number of samples foreach waveform (for example at 4.41kHz, a sine waveform will beapproximated by only 10 points). Therefore this is forfun/educational use, for critical applications use a realcalibrated function generator.Left and Right audio channels can beassigned to either channel 1 or channel 2.Sine, Square &Triangular waveforms.Frequency range from 1 mHz up to 22kHz.Amplitude as percentage 0-100%.Set duty for square waveforms orskew triangular waveforms to get saw waveforms.Offset the phase ofwaveforms.Sweep frequency or amplitude (Single, Repeat & Bouncemodes).Amplitude Modulation (AM).Frequency Modulation (FM).Burstmode for a specific number of waveforms (1-10000).White noise &pink noise Generator. Pink (1/f) noise falls of at ~3dB per octavebetween 43 Hz and 44 kHz. Memory slots to save & recall channelconfiguration.Select values with spring slider or number pad.Moredetailed explanation available on website

Ads shown on exiting apponly. If you dislike these ads, there is an option to turn them off(enabled after 6 hours) in the settings menu (top left button).

Straightforward guitar tuner. Single screen app that starts in autotune mode. Simply run the app, hit a string and start tuning yourguitar. Tune into the orange region for a good results or green forperfection.This app uses your microphone to detect the string beingplayed and indicate if you should tune up or down. Pitch pipefunction also included. The standard EADGBE guitar (not implementedfor very small screen devices) indicates current note being playedor allows fast note selection in manual mode. Tuning range from 30Hz (B0) to 4186Hz (C8), so can also be used to tune other stringedinstruments.

This app uses the magnetic field sensor on your device to measuremagnetic flux density (B) in Gauss or Tesla. FOR INDICATION ONLY.Results depend on your device and its hardware.

Sound Spectrum Analyzer meters sound noise level (SPL - amplitudein decibels) and analyses sound frequency spectrum in real time(RTA) using FFT. The analyzer is very easy to use and offers a lotof useful features: high RTA refreshing rate and frequencyresolution, adjustable sound noise level amplitude scale (up to 150decibels), RTA peak hold function, flat reference line, local peakfrequency... Sound meter can be recorded on 3 separate channels.User can later compare noise level (SPL - dB) and frequencyresponse charts between the channels. It also includes a signal(tone) generator, which helps us to meter the frequency response ofa sound system. Input/output can be adjusted to Internal, AUX orBluetooth. However, all I/O options and combinations do not work onall devices. Meter can be accurately calibrated for each frequencyband separately.

Spectroid is a real-time audio spectrum analyzer with reasonablefrequency resolution across the the entire frequency spectrum.💬 FAQ💬Q: Why are the dB values negative?A: Spectroid uses dBFS (FullScale) where 0 dB is the maximum power that the microphone canmeasure, so the decibel values are negative because the measuredpower is less than the maximum power.Q: Can I zoom in on thespectrum plot?A: Yes, do a two-finger pinch-to-zoom gesture.Q: Whyare there discontinuities/gaps in the spectrum plot andwaterfall?A: Spectroid uses multiple FFTs overlapped in frequencyin order to provide better frequency resolution at lowerfrequencies than a single FFT. The caveat of this method is variedimpulse response and minor discontinuities in frequency. The upsideis that it can efficiently produce a spectrum that better matchesthe frequency resolution of human audio perception. It's stillprobably not as good as your ears though!

Hz Generator is the perfect tool for testing audio systems.You canalso use it to prank your friends!- Generates mono sine waveaudio.- Use it as a simple 50 Hz test tone or pick anotherfrequency.- Configurable from 20 Hz up to 20 000 Hz!Easy to use:-Set the frequency with slider or buttons- The power button togglesaudio on and off.- Adjust volume using device volumecontrols.DISCLAIMERAlways remember to turn the volume down on yoursound system before connecting and turning Hz Generator on. Allfrequencies are not playable on all devices/audio systems. Allfrequencies cannot be heard, but can be harmful if too loud. Alsobe kind to animals and neighbors.

Simply generate a tone with a frequency between 1Hz and 22000Hz onyour smartphone or tablet. Simple and Accurate Use the cursor orthe keyboard of your smartphone to adjust the frequency, then click"PLAY" to play the tone. Multiple use cases • Test your hearing andthat of your surroundings by determining the range of frequenciesthat you are able to hear. On average, the human ear perceivesfrequencies between 20Hz and 20000Hz, but this perception candeteriorate with age, especially for frequencies close toultrasound. • Experience the acoustic beat phenomenon: For example,launch the application on two devices and then generate a frequencyof 440Hz on one and 443Hz on the other. You will then hear a "beat"of frequency 3Hz. This phenomenon is frequently exploited bymusicians to tune their instruments by ear. • Test your speakersand other audio devices. • You may try to use this app as amosquito repellent app (anti mosquito), but be aware that severalscientific studies have found that ultrasounds are not an effectivesolution to repel mosquitoes. Anti mosquito apps usually try torepel mosquitoes by generating near ultrasounds and ultrasounds(between 15000 Hz and 22000 Hz). • This sound generator cansimulate a dog whistle to help you train your dog by producing veryhigh pitch sounds. • Remove water from your phone speaker. If yourphone is water-resistant and has been in contact with water, thespeaker may now sound muffled. The vibrations caused by thegenerated frequencies will help unclog the water and repair yourspeaker. Advanced Mode Enable the Advanced Mode in the app menu toaccess the following features: • Change the generated signalwaveform: sine, square, triangle or sawtooth. • Play a tone basedon specific musical notes. And like every good sound generator, thetone will be generated in background if the associated option isenabled in the app menu. Keep in mind that the generated tones canbe very annoying and irritating for your surroundings. Always usethis application responsibly. Note: When generating ultrasonictones (20000 Hz and more), your device's speaker may produceadditional parasitic sounds. Hearing those sounds does not mean youcan hear the actual frequency being played.

Sound Analyzer App lets you use your smartphone as a Sound LevelMeter (SLM) and a Real time Audio Analyzer (RTA). Environmentalnoise, measured in decibel (dB) can be monitored in real time.
